Methods
__construct
Constructor.
data
array
Optional. Data for populating the Message object.
↳ base_ejection_time
Google\Cloud\Compute\V1\Duration
The base time that a host is ejected for. The real ejection time is equal to the base ejection time multiplied by the number of times the host has been ejected. Defaults to 30000ms or 30s.
↳ consecutive_errors
int
Number of errors before a host is ejected from the connection pool. When the backend host is accessed over HTTP, a 5xx return code qualifies as an error. Defaults to 5. Not supported when the backend service is referenced by a URL map that is bound to target gRPC proxy that has validateForProxyless field set to true.
↳ consecutive_gateway_failure
int
The number of consecutive gateway failures (502, 503, 504 status or connection errors that are mapped to one of those status codes) before a consecutive gateway failure ejection occurs. Defaults to 3. Not supported when the backend service is referenced by a URL map that is bound to target gRPC proxy that has validateForProxyless field set to true.
↳ enforcing_consecutive_errors
int
The percentage chance that a host will be actually ejected when an outlier status is detected through consecutive 5xx. This setting can be used to disable ejection or to ramp it up slowly. Defaults to 0. Not supported when the backend service is referenced by a URL map that is bound to target gRPC proxy that has validateForProxyless field set to true.
↳ enforcing_consecutive_gateway_failure
int
The percentage chance that a host will be actually ejected when an outlier status is detected through consecutive gateway failures. This setting can be used to disable ejection or to ramp it up slowly. Defaults to 100. Not supported when the backend service is referenced by a URL map that is bound to target gRPC proxy that has validateForProxyless field set to true.
↳ enforcing_success_rate
int
The percentage chance that a host will be actually ejected when an outlier status is detected through success rate statistics. This setting can be used to disable ejection or to ramp it up slowly. Defaults to 100.
↳ interval
Google\Cloud\Compute\V1\Duration
Time interval between ejection analysis sweeps. This can result in both new ejections as well as hosts being returned to service. Defaults to 1 second.
↳ max_ejection_percent
int
Maximum percentage of hosts in the load balancing pool for the backend service that can be ejected. Defaults to 50%.
↳ success_rate_minimum_hosts
int
The number of hosts in a cluster that must have enough request volume to detect success rate outliers. If the number of hosts is less than this setting, outlier detection via success rate statistics is not performed for any host in the cluster. Defaults to 5.
↳ success_rate_request_volume
int
The minimum number of total requests that must be collected in one interval (as defined by the interval duration above) to include this host in success rate based outlier detection. If the volume is lower than this setting, outlier detection via success rate statistics is not performed for that host. Defaults to 100.
↳ success_rate_stdev_factor
int
This factor is used to determine the ejection threshold for success rate outlier ejection. The ejection threshold is the difference between the mean success rate, and the product of this factor and the standard deviation of the mean success rate: mean - (stdev * success_rate_stdev_factor). This factor is divided by a thousand to get a double. That is, if the desired factor is 1.9, the runtime value should be 1900. Defaults to 1900.
getBaseEjectionTime
The base time that a host is ejected for. The real ejection time is equal to the base ejection time multiplied by the number of times the host has been ejected. Defaults to 30000ms or 30s.
hasBaseEjectionTime
clearBaseEjectionTime
setBaseEjectionTime
The base time that a host is ejected for. The real ejection time is equal to the base ejection time multiplied by the number of times the host has been ejected. Defaults to 30000ms or 30s.

getConsecutiveErrors
